You can also fix with '''[Edit Mode] Mesh> Clean Up> Merge By Distance''', and then put a solidify modifier at 00.1 thickness. | You can also fix with '''[Edit Mode] Mesh> Clean Up> Merge By Distance''', and then put a solidify modifier at 00.1 thickness.

Alternately, select all, alt+n to average face area. If any blue lines on the edges appear, select edges, then 'clear sharp' and alt+n average face areas again. | |||

Unfortunately physics are not quite at game quality yet at this stage. | Unfortunately physics are not quite at game quality yet at this stage. | ||
Physics are set with red vertex paint. Hot pink vertex paint counterbalances the physics. | Physics are set with red vertex paint. Hot pink and blue vertex paint counterbalances the physics. | ||
If a mesh is 100% weighted to a single bone, adding physics will cause it to crash the game. If you are making a helmet item and therefore need it to be entirely static, weight some of it to the piercing bones as they also do not move. | |||
A mesh cannot be entirely vertex painted red or it will bounce around, it needs some black vertex paint left to keep it in place. | |||
If your mesh is creasing up at the back, you may want to lower the vertex paint to be lower down. | |||
A cloth mesh (Generally named something like HUM_F_CLT_Daisy_Dress_A_Cloth_Mesh and will import in) is the collider mesh, which stops it clipping through things. Sadly you may need to delete it as it can cause your mesh to be exported with errors. | A cloth mesh (Generally named something like HUM_F_CLT_Daisy_Dress_A_Cloth_Mesh and will import in) is the collider mesh, which stops it clipping through things.

Some people have had success pasting the code from in game meshes into their lsx mesh code, specifically clothbuffer values, which caused the physics to be less flappy and enabled the collider mesh to be exported without issues. Which is worth a try if you have a lot of patience and experience with coding.

Some people have also experimented with not exporting the mesh and setting non-skirt parts of the original mesh to use an invisible material, then combining it with their own torso in a roottemplate. | |||
